Specification of Letters Patent. Pat ted Get. 11, 1910.

Application filed Has-ch 2! 1910-. Serial No. 551,993;

To all-whom it may concern:

.Beit known that I, CARL GUSTAF Osoan- GREvmLrUs, a subject of the King of Sweden, residing at Stockholm,- in the Kingdom of 5 Sweden, haverinve nted new and useful Tmprovements in Firearms, of which the following is a specification, reference being had to the drawing accompanying and forming a part hereof.

Ofall' the devices at the present date in use for operating the safety of fire-arms, or the lockwork of multi-barreled combinationguns, none has proved to be more popular than the slide or button on top of the tang.

'This device, although for handiness it can hardly be surpassed, has two drawbacks, each of which implies a serious danger. For one thing, it is extremely difficult to see, or

, otherwise to ascertain, whether the gun is safe or not.' This difliculty increases, if the slide can be moved into more than two positions. The small letters generally imprinted on the tang are utterly useless in guarding against accidents. For the other thing, the slide is too much exposed to being accidentally moved into an unsafe position bycatching against coatbuttons, twigs, etc.

The object of the invention is to remove the said drawbacks and provide a gun in which the safety may be easily handled and the position of the same may be easily ascertained by a slight touch with the thumb.

The invention consists in certain novelfeatures of construction and combination of parts of the fire-arm all as hereinafter fully described and claimed.

In the drawing, I have shown one Way of q applying my invention to a three-barreled gun with three locks and only two triggers 40 requiring a slide movable into three difi'erent positions.

Figure 1 is a longitudinal section of a part. of the gun, showing the parts in safe-position. Fig-2 is a cross-section. Fig. '3 is a top plan View of part of the lockwork. Fig. 4 is a longitudinal sectional view showing .the slide in one end position and safety unbolted. Fig. 5 is a longitudinal sectional View showing the slide in its opposite end position and safety unbolted.

Referring to the drawing, the. slide a, on top of the tang, can be moved from its midposition either forward or backward. In each position it is heldin place by a spring 5 Z).- The slide act'uates the rocking-lever (l which is pivoted on the pin 0. When the touch of the thumb at an slide 0, and the lever (Z are in their mid-positions, Fig. 1, both triggers e and f are positively locked by the lever d, and thus the gun is safe. Fig. 4: the releasing latch g sliding on the top of the righthand trigger e arrives undcrneath the sear h of the righthand lock, and both tri gers e and f being at the same time unbolted, the righthand hammer may be snapped by means of trigger e and latch 9.

By pulling the slide a back, Fig. 5, the latchg arrives underneath the shorter sear i of the intermediate lock, andboth triggers e and 7 being even in this case. unlocked, the. inter-. mediate hammer maybe snapped by means of tri ger e and latch g.

The lefthand trigger f, if not locked, always actuates the sear is, Fig. 3, of the lefthand lockwhich, consequently, may be pulled ofi" whenever the slide a isbrought lnto either end-position.

In Fig. 1, showing safe-position, the slide a is inclosed between the immovable lugs I, Fig. 2, slide and lugs presenting together, to view and to touch, a comparatively smooth surface from which twigs and such like things will glide off, without moving the slide. The human thumb however, being just soft enough, will find no difliculty in pressing the slide over into either end-position, shown in Figs. 4 ahead. The slightest time will sufiice to ascertain the position 0 the slide.

In most arms the slide can be moved into two positions only, effecting the safety of ordinary double guns or actuating the reve'rsing gear in combination guns. In either case the lugs Z are equally applicable and equally useful. Thesafety of the arm might be effected by bolting the hammers, the mainsprings or the sears, either or all.

If desired, the slide a may be replaced.

by a lever, for instance by an upper extensionof the rocking lever d. The lugs the slide, or the lever may obviously be dlfi'er- By pushing the slide a forward,

ently shaped in an endless variety of forms, I the lugs for instance forming a rather ex-, 9

tended elevated surface.

Iclaim: I

1., In a fire-arm, the combination of a safety-slide adapted to take up a middle position in which the arm is made safe and two unlocking positions, and a lug projecting above the surface of tang and extending along the said slide, at one side thereof, and forming together with the upper surface of one or the other firing mechanism according as the slide takes up one or the other unlockmg posltion.

8. In a multi-barreled fire-arm, the combination of firing mechanisms for the different barrels, triggers for operating the said firing mechanisms, a safetyslide adapted to take u a middle position in which the arm is ma e safe, an elevated surface forming a continuous extension of the said slide in-the said middle position thereof, and means op- I erated by the said slide for operatively connecting one trigger with one or the other firing mechanism accordin as the slide takes up one or the other unloc 'ng position.
